y <- 2 - (x[,1] > x[,2])
you can also do
cbind(x,y)
if you wish.

Hi,
I have the following (M x N) matrix, where M = 10 and N =2
What I intend to do is to group index of (M) based on this condition
of "x_mn" , namely
For each M,
If x_m1 > x_m2, assign index of M to Group1
otherwise assign index of M into Group 2
> x
[,1] [,2]
[1,] 4.482
